Rolling bearing for automatically adjusting gaps of steel balls

Abstract

The invention discloses a rolling bearing for automatically adjusting the gap between steel balls, which comprises: a bearing outer ring and a bearing inner ring. Ring steel balls, the two sides of the steel balls are respectively provided with annular elastic cover plates, the inner sides of the annular elastic cover plates are respectively provided with cages corresponding to the steel balls, and the side of the cages close to the steel balls is provided with an adjustment mechanism , the adjustment mechanism includes a horizontal column and a spherical roller, one end of the horizontal column is fixed inside the cage, and the other end is provided with the spherical roller, and the outer circle of the spherical roller is attached to the steel ball. Through the above method, the rolling bearing for automatically adjusting the steel ball clearance of the present invention can automatically fasten the steel balls and adjust their rolling positions when the steel balls are worn out, so as to ensure the normal operation of the steel balls and improve the service life of the bearings.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a rolling bearing for automatically adjusting the gap between steel balls. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during the movement of the mechanical rotating body, and ensure its rotation accuracy. [0003] According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and the price is also higher. . [0004] Bearing steel balls are prone to wear and tear after rolling for a long time, resulting in a larger movement gap of the steel balls and affecting the service life of the bearings.
